IMPROVEMENT IN KNlEE-SHARPENER S.`

Specification forming part of Letters Patent No. 116,495, dated J une27, 1871.

To all whom it may concern:

Be it known that I, JAMES J. RUss, of the city and county of Worcesterand State of Massa-chusetts, have invented certain new and usefullmprovements in Knife-Sharpeners; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawing Which forms part of this specification,and in which- Figure 1 reprcsents a side view of my improvedknife-sharpener, and Fig. 2 represents, upon an enlarged scale, acentral longitudinal section at line A B, Fig. l. i

To`enable those skilled in the art to which my invention belongs to makeand use the same, I Will proceed to describe it more in detail.

The nature of my in vention consists in the combination, with theholding-frame, constructed as described, of the cutter and itsholding-screw, as hereinafter set forth.

In the drawing the pa-rt marked A represents the holding-frame, whichconsists of the head A' and handle B. 1 Said frame is made of metal andin the form shown, the head A' being provided with a pair of horns, a a,projecting from the upper part thereof, while the lower part is formedsquare across, so that it Will rest firmly upon a table or othersupport, when desired. The head A' and handle B may be cast more or lessornamental, to suit the taste of the manufacturer. A Vertical opening isformed through the head A', centrally between the horns a a, to receivethe cutter (J, which latter is formed of a small bar of steel, with itsedges Slightly beveled so as to present two sharp corners. This cutteris arranged in the opening of the head, and projects up between thehorns a a in such a manner as to form equal angles between the sharpcorners of the cutters and the inner'side of each of the horns.

The sides b b of the opening are formed-on the same bevel as the sidesof the cutter C, and the lat-ter is secured in position by means of aholding-screw, D, which screws through the side of the head A' againstthe cutter C, thereby pressing the beveled edges of the cutter againstthethe case when the cutters are secured upon the side of theirsupporting-blocks. The cutter C can be adjusted up or down as its edgesbecome worn by simply loosening the holding-screw D and sliding cutterwithin the opening.

When sharpening a knife the operator takes hold of the handle B with hisleft hand and rests the head A' upon a table or other support; then withhis right hand he draws the edge of the knife to be sharpenedalternately through the angles between the horns a and the cutter, andthe sharp corners of the latt-er shave off the metal at the sides of theknife-blade, and produce the proper sharpness of edge. p

Having described my improved knife-sharpener, what I claim therein asnew and of my invention, and desire to secure by Letters Patent, is-

The combination, With a holding-frame in a knife-sharpener provided Withsupporting-bevel's b b, of the beveled-sided cutter U and pressingscrewD, substantially as shown and ,described JAMES J. RUSS.
